CARRIER FOR PNEUIlIATIC-DISPATCH SYSTEMS.

Application filed June 15, 1928. Serial No. 116,242.

This invention relates generally to the con struction of carriers for pneumatic dispatch systems.

In the operation of pneumatic dispatch installations such as re provided in department stores and similar places, it is frequently necessary to inspect the contents of the carriers before they have reached their final destination. An instance of this is in the distribution of carriers among credit authorizing clerks in accordance with group divisions of the alphabet to which customers names appearing on the slips in the carriers correspond. The opening of the carriers and removal of the contents foninspection, followed by the replacing of the slip in the car rier for delivery to the proper authorizer, have been wasteful of time and destructive of efficiency of operation.

It is a general object of the present invention to provide a carrier construction which will be free from the objections referred to and which will provide for the. inspection of slips contained in the carriers without opening the carriers and removing the slips therefrom.

The invention includes the'provision of a carrier permanently open at one end and having a sight opening in a side wall through which a slip passed into the carrier shell through the end opening can be inspected by a distributing operator.

Another feature of the invention resides in the provision of a spring member between which and the apertured. side wall of the shell a slip may be passed and maintained in position to present matter for inspection through the aperture or sight opening. The spring member referred to preferably has a looped formation attached at one end to the inner end of the carrier and with its formed outer end occupying a position in the open end of the carrier to thereby facilitate the in sertion of the slips in display position.

To further facilitate the insertion of slips into the carrier, the sight opening referred to has an egg-shaped formation, with the smaller end leading away from the open end. of the carrier to thereby prevent restrictive engagement of the edges of the opening with movement of the slips into display posit-ion.

Other features of the invention will be hereinafter referred to,

bodiment of the invention has been selected for illustration:

Figure 1 is a plan view of a pneumatic dispatch carrier embodying the invention.

Figure 2 is a view in vertical horizontal section of the carrier shown in Figure 1.

Figure 3 is a face view of the closed end of the carrier shown in Figure 1.

Figure l is a view in transverse section of the carrier shown in Figure 1.

Figure 5 is a. view in side elevation of the carrier shown in Figure 1 and indicating the manner of inserting a slip in the carrier.

Figure 6 is a view similar to Figure 1 showing a modified form of the invention.

Figure 7 is a. view in longitudinal section similar to Figure 2 showing the form of the invention shown in Figure 6.

Referring to the drawings for a more detailed description of the invention, a. pneumatic dispatch carrier is shown which consists'of an outer cylindrical shell 10, and an inner shell 11, each of which are closed at one end to form a seat 12, to which a felt buffer 18 is attached.

The other end of each shell is open, the outer shell 10 being provided with an end flange 14:, and the outer end of the inner shell 11 being provided with an end flange 15. The flanges 14 and 15 are spaced apart longitudinally of the carrier to provide a seat in which a felt buffer 16, of annular formation is received and grippedor clamped between the flanges.

An aperture or sight opening 17, is provided in the wall of the carrier through which a name 18 or other matter on a slip 19, contained within the carrier may be displayed.

In order to hold the slip 19 in display position, a looped flat spring member 20, is attached at one end to the closed end of the inner shell 11, by anchoring engagement with a metal strip 21, locked beneath nuts 22, on the inner ends of bolts 23, which serve to hold the felt buffer 18 on its seat and to clamp the closed end portions of the shells in contact and thereby also clamp the buffer 16 between the flanges 1 1 and 15.

The spring member 20 is arranged to extend across the aperture 17 in the side wall of the carrier and with the bound outer end 24 disposed in the open end of the carrier. With this arrangement it will be seen that a slip of paper 19 may be readily inserted between the curved outer end at the spring member 20 and the inner face of the wall of the carrier, the spring then acting to hold the slip in engagement with the surface of the carrier wallfor inspection through the sight opening 17.

In order to further facilitate the insertion of the slip 19 into position in the carrier, the sight opening 17 has an ovoid or egg-shaped formation with the smaller end 25 of the opening niost remote from the open end of the carrier. The converging edges of the opening which are thus provided prevent restrictive engagement of the edges with the advancing paper. In Figure 5 of the drawings, there is indicated a method by which the slip may be readily inserted, the thumb 26 of the operators hand serving to depress the spring and at the same time advance and guide the slip into display position.

In the modified form of the invention shown in Figures 6 and 7, a cylindrical member 27 formed of transparent celluloid or similar material is inserted in the tubular container as is clearly shown in these figures. The use of the transparent liner 27 obviates all chance for the edge of the paper slip to come into contact with the edges of the sight opening 17. The member 27 may take the form of a simple rectangular section of celluloid which is merely bent into cylindrical members and open at one end, said shell being provided with a sight opening in the side wall thereof, and a looped spring member attached to the inner closed end of the shell and having its bowed outer end lying in the open end of the shell, whereby a slip of papermay be inserted between the spring member and the side wall of the shell to malntain the slip in display relation to the sight opening.

2. A carrier for pneumatic dispatch systems comprising a pair of tubular shells fitted one within the other and open at one end, each of said shells having an outwardly flanged open end and said flanges being spaced apart longitudinally of the shell, an annular bufl'er member seated in the space between said flanges, a buffer member attached to the closed end of said shells, said shells being provided with a sight opening in the side wall thereof, an elongated flat spring member attached to the inner closed end of the shells and extendi'ng along the opposite inner surfaces of the shell and across the sight opening, and the outer curved end of the looped spring member lying in the open end of the shells whereby a slip of paper can be readily inserted be.- tween the spring member and the side wall of the shell to arrange the slip in display relation to the sight opening.

3. A carrier for pneumatic dispatch systems comprising a shell open at one end, said shell being provided with an egg-shaped sight opening in a side wall thereof, with the smaller end of the opening directed away from the open end of the shell, and spring means arranged to press against the side wall of the shell containing the sight opening but permitting a slip of paper to be inserted at the open end between the spring and side wall of the shell and moved along the wall to display position with relation to the sight opening.
